Egg sharing

The generous act of egg donation could benefit both you and the potential recipient of your eggs.

Some women require donated eggs as their own egg quality may be poor or they may no longer produce any eggs. Egg sharing is a widely used treatment, whereby someone needing fertility treatment, who have a normal ovarian reserve  (see A-Z of Fertility) donates half of her eggs produced in an IVF cycle, to a woman needing egg donation. The woman donating her eggs receives free IVF treatment for herself. There is no doubt that egg sharing is a life changing gift and needs to be considered carefully.

Types of egg sharer

There are two types of egg sharer:

  • Altruistic egg sharers (who give some of their eggs to someone they don’t know)
  • Known egg sharers (who give some of their eggs to someone they know needs them in a cycle of their own)

Who can be an egg-sharing donor at Simply Fertility?

To be an egg-sharing donor at Simply Fertility, you must:

  • be less than 36 years of age (i.e. treatment cycle must finish before the 36th birthday)
  • have an AMH value of at least ≥15.0 pmol/L (showing a good ovarian reserve – on ultrasound)
  • have body mass index of less than 30
  • be a non-smoker
  • test negative for various infectious diseases and have a normal genetic analysis

If you are interested in becoming an egg sharing donor, please contact the clinic on 01245 241231.

You will need to undergo one of our Fertility Assessment packages to discuss your treatment and to confirm your eligibility to be an egg donor

Specific requirements for egg-sharing donors

The aim is to donate a minimum of 4 eggs to the person receiving your eggs. The recipient can receive your eggs either fresh (when her menstrual cycle has been coordinated with your treatment cycle) or the eggs can be “vitrified” (frozen) to be used at a later date. The eggs are shared between you (the egg-sharing donor) and the recipient. The number you each receive depends on how many eggs are available.

Your commitment as an egg sharer

As the egg-sharing donor – whether you know the recipient or you are donating altruistically – you make a formal commitment to share a number of your eggs, depending on how many we collect. If you decide to keep all your eggs, you are liable for the full treatment costs of a standard cycle.

NB. Both you and the recipient should be aware that you as the donor are free to withdraw consent to donate your eggs, or to transfer embryos derived from those eggs, at any time up until they are transferred to the recipient.

How the eggs are shared

It’s our policy to try to ensure that your chances of pregnancy are not reduced by donating some of your eggs. As long as the egg-sharing donor retains at least 4 eggs for her own use, our data shows that the donor has no reduction in her expected chances of pregnancy in her fresh treatment cycle.

NB. If the clinical team decide that your ovaries are not responding adequately during stimulation monitoring, and not enough follicles are developing, we’ll cancel the stimulation cycle. This is unless you want to continue with treatment for yourself without attempting to share eggs, in which case you’ll pay for all treatment and drug costs, as in a standard IVF cycle.


You need to undergo some screening tests to make sure there’s no reason why you can’t be an egg sharing donor. You can learn more about the types of test on the Fertility Assessment page, or call the clinic for more information.
